Would armor spikes get your Strength bonus to damage, i know if you attack with them they would...but what about the automatic damage from making a successful grapple check?
Seeing that strength is utalized in making your CMB roll to make the grapple, I would say yes. You're squeezing them extra hard into your spikes.
Dont think so.. just regular damage
ok thanks, i figured it would because, like it was said above you are squeezing harder, but I wanted to make sure there wasn't a passage somewhere in the book i was missing
